'To all whom it may concern:

Be it known that LiHENRY Bass, :1 citi- Zen of the United States, residingat Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Anti ly-rotatable' parts, such as shafts and their housings. In the use of thrust bearings for this p n-pose, it is customary to employ separating means for the rolling elements of the Hearings, .which separating means are common y in the form of a, plate or cage with seats or sockets in which the rolling elements revolve, and WlilClB plate is arranged between the relatively rotating parts so as to rotate between them as the rolling elements; are individually revolved by contact with said parts In practice more or less trouble results, due to the cage riding on the shaft or on the housing, or due to the weight of the cage having to be carried by the rolling elements when not traveling on the shaft or housing. This trouble becomes more pronounced when there is an occasional relief of the load or recession of one of the relatively rotating parts from the. other, allowing thee-agrewith the rolling elements to drop, which latter are forced up when the parts approach each other as the load comes on again. The accidental strains due to these objectionable actions are apt to he very severe and are decidedly injurious to the hearing. If, in order to pre: vent the lateral shifting of the cage and rolling elements as (lescriberhthe cage is allowed to ride on either the shaft or housing, more or less injurious wear will occur at this point, particularly when the parts are driven at-high speeds. In order to obviate ,these objectionable actions, I provide the cage in accordance with my invention, either where it surrounds the shaft or where it fitswvithin thehousmg, with an 'extcnded portion arranged in close proximity to the housing on-shaft as the case may he, so as to give effectual support to the cage and prevent the same ,from injurious wear or from lateral shifting. In its preferred and more specific form, the extension on the.

"cage is in the form of ac'ylintler and is ac. V curatel y turned or ground;toileaye only a.

small clearance"hetiveen it and thesuppolnt-' Qing-"iart, as a result of which construction I an oil him will he formed whichlWil-l s tain the cage in its proper,position andiree from injurious rear; I

In the accompanying drawings" 1' have shown any improved cage as belnghsu pported by a. fixed housingsurrounding a ro-. tery part or shaft, but it will be understood that the invention contemplates as well the formation of the cage so that it will colitierate with and be supported by the sha-ftf; I

and it will he further understood that my invention is not limitedto-any particular form or construction of the ,partsh. ept so far as such limitations aresp'ecifiedin" the claims. I I

antifriction hearing having my embodied tl'icrcim- Fig. 2 is an elevation i v 75, In the accompanying drawingsz'Figdre 1' of the cage or separator removed from the bearing.

In the particular embodiment of my invention shown, [represents a rotary shaft, and 2' a fixed housing surroundingthe shaft.

3 represents an an'rifrictiou device in the form of a thrust bearing comprising-a thrust plate 3* carried by the shaft,- a thrust-plate 3" sustained by the housing, and a series of interposed rolling elements 3 in the form of frirtion halls, which travel in grooves-in the adjacent faces of the plates 3', and 3". The friction halls arer mounted in socketsor openings in a circular'plale or disk 4. loosely surrounding the shaft and arranged between the thrust plates. the disk serving to main tain the rolling elements in stiaced relation, and forming a cage for the same, which cage is rotatable as a whole around the shafts axis. as the balls are rotated individually in the case by the contact of the thrust plate 3 with the balls The forcgoiujlparts may be of the usual and ordinary construction, and constitute a well-known form of thrusthearing by which the end thrusts of the shaft are received and transmitted to the surrounding housing.-

in carrying out my invention in its preferred form. form on the periphery of the Whic'hlf io ects in opposite directions from the plane of the cage, a considerable distanccbeyond the ball diameters, so as to form an extended cylindrical shell, the outer surface of which. fits loosely but Closely within the housing 2 and receives ell'ectual support therefrom. This cylindrical extension is preferably accuratelv turned or ground on its exterior surface and is of such diameter relative to the housingas to leave only a small clearance between it and the housing, so that its fit within the housing will be such as to cause the formation of an oil film between the housing and the ex ternal cylindrical surface of the cage. As a result of the construction described, the cage will be effectively and evenly sup orted, and therefore prevented from shiftmg laterally out of its true position with reference to the ball tracks on the thrust plates. Furthermore, the broad andextended cylindrical supporting surface on the cage, by cooperation with the housing, causes the cage to travel around in an even and uniform manner, and free from injurious friction or wear. The provision of the oil film, enables the cvlindrical surface of the cage to move inverv close proximity to the surrounding surface of the housing without danger of seizing, and with a freedom of motion which will not interfere with the proper operation of the bearing as a whole.

lVhile in the drawings the relatively moving parts are, shown as horizontally-disposed, and while in the claims these parts are so referred to, it will be understood that the substantial horizontal disposition of. Hip I relatively moving parts would be within the scope of my invention, or in fact, any (118 pcsition of the parts from the horizontal,

which would bring about the action of grav ity in its tendency to shift the cage laterally.'

l-laring thus described my invention, what I claim is:

The combination of two horizontally disposed parts, one rotatable relatively to the other and one part being exterior to the other and provided with an internal smooth cylindrical surface, a thrust bearing disof the bearing and formed withopenings in.

which the rolling elements are seated, said plate being provided at its peripheral edge with annular flanges extending in opposite directions for aconsiderable distance beyond the rolling elci'nents, the outer faces of said flanges forming a smooth, continuous cylindrical extended bearing surface titting in'such immediate proximity to said interior cylindrical surface as to admit of the formation of an oil film between said sur-- face.

In testimony whereof I allix my signature in presence of two witnesses.
